3 Occupatinal health Increasing rle in supprting peple t get back t wrk in gd health Knwledge f the wrk envirnment, and the risks fr health and safety Preventin fr lng-term sickness absence? Depending n the cntext, is return t wrk pssbile?

4 Occupatinal health Re-integratin trajects (started by emplyee, emplyer, physician f mutuality) Pssible t resume the agreed wrk eventually (A) Capable t execute adapted wrk in the meantime (B) Nt capable t execute adapted wrk in the meantime Same cmpany Uncapable t resume the agreed wrk ever (C) Capable t execute adjusted wrk within same cmpany (D) Nt capable t execute adjusted wrk (E) Fr medical reasns nt pssible t start reintegratin (at the mment) Different cmpany

5 The screening instrument Screen fr the risk fr lng-term sickness absence Wrk-related risk factrs Persn-related risk factrs Stressful life-event related risk factrs Functining-related risk factrs Generic triage instrument applicable in all cntexts and fr all diseases

6 Methds Prcedure In- and exclusin criteria Questinnaires sent t ccupatinal health physicians via CPrev June-Octber 2017 Patients: questinnaire, apart frm the physician Physician: shrt questinnaire abut his estimatin regarding the patients health Inclusin criteria patients: Being n sick leave Appintment with ccupatinal health physician cncerning RTW French r Dutch speaking Exclusin criteria patients: Nt n sick leave Appintment fr ther reasn than RTW

7 Statistical analysis SPSS and AMOS24 Datascreening fr multicllinearity (negative) Descriptive statistics Reliability (chrbach s alpha) Cnstruct factrial validitiy (cnfirmatry factr analysis) Criterin -cncurrence validity (Path analysis)

8 Descriptive statistics Sex (65% wmen) Language (86.2% NL) ISCO prfessin ICD-10 scale 276 respndents Educatinal level 38.4% upper secndary diplma 25.4% bachelr degree 7.2% universitary degree

9 Descriptive statistics (1) muskulskeletal diseases (54%) (2) Mental and behaviural disrders (25.5%) 4.6% multiple diagnses 6.2% n (clear) diagnsis

10 Descriptive statistics Prfessinals (39%) Elementary ccuapatins (20.9%) Smallest grup: managers (2.4%) Abut 40% healthcare wrkers

11 Reliability All scales were reliable (>.70) Except fr the perfectinism scale (.62)

12 Factr analysis: cnstruct validity (factrial validity) One factr analysis fr each cluster f factrs Wrk-related Functin related Persn related Stressful life event related CFI, NNFI, RMSEA, SRMR, χ2 difference test Factrial validity was satisfying: the mdels supprted the data well

13 Path analysis: criterin validity (cncurrence validity) Relatin between estimatin physician and factrs frm questinnaire Multiple item factrs: mean scre Path analysis fr each cluster f factrs Wrk-related Functin related Persn related Stressful life event related

14 Path analysis: criterin validity (cncurrence validity) 8/20 factrs significantly (p<0,05) related t the estimatin f the ccupatinal health physician regarding return t wrk (=30/59 questins) 1. physical wrklad (ρ=.001) (7Q) 2. scial supprt frm clleagues (ρ=.012) (2Q) 3. wrklad (ρ=.016) (7Q) 4. develpment- and learning pprtunities (ρ=.014) (2Q) 5. return-t-wrk perceptin (ρ=.047) (1Q) 6. health perceptin (ρ=.032) (2Q) 7. stressful life events (ρ<.001) (8Q) 8. return-t-wrk needs (ρ<.001) (1Q)

15 Discussin Mre validatin prjects are planned t cmpletely validate the instrument First results are prmising Actual time until return t wrk shuld be measured (= mre precise than estimatin f the physician)
